Product Description

The Westin 19-44745 Hard Tri-Fold Tonneau Cover is purpose-built for 2020-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 79.4-inch long bed. Constructed from heavy-duty aircraft-grade aluminum panels on an extruded aluminum alloy frame, it delivers the structural strength and security of a hard cover while maintaining the everyday convenience of a tri-fold system. Squeeze-lever-activated panels fold back in three sections, allowing partial or full bed access in seconds without removing the cover.

The cover mounts flush with the bed rails using a custom-fit, no-drill under-bedrail clamp system, maintaining a clean OEM appearance while reducing aerodynamic drag. Full-perimeter EPDM rubber seals and an integrated drainage system work together to keep the bed dry and protected in all weather. Backed by a limited lifetime warranty and rated to 661 lbs. of evenly distributed static weight, the 19-44745 is a dependable long-bed solution for the current-generation Silverado and Sierra 1500.
